Explore InfiniBand physical connectivity by linking compute and GPU nodes from multiple vendors via host channel adapters or embedded adapters to an InfiniBand switch.
Explore two-node InfiniBand connectivity on Ubuntu, using a switch or a direct DAC cable, install and validate drivers with OFED or RDMA, and perform fabric discovery with a subnet manager.
Understand local identifier (lid), a 16-bit InfiniBand port address used for subnet-wide, fast routing in a flat network, distinct from GUIDs and assigned by the subnet manager.
Download the appropriate mlx ofed package from nvidia, extract it, and run mnx ofed install with add kernel support to install drivers and update firmware, then verify with ofed info-s.
